NETRIVER - Intelligent Data CentersInnovation for Ultra High Efficiency

Published: September, 29 2014

"PSR Mechanical has been an excellent partner for NetRiver. Their focus on continuous improvement to our system, while working within our tight timeframes has been an essential part of our ongoing growth strategy."

~ Paul Harris - Vice President & GeneralManager, NetRiver Int. LLC


  • 30,000 sq. ft. total area
  • 500 Tons air-cooled capacity
  • 300 Tons water-cooled Capacity
  • 30 Tons air-side economizer
  • 350 Ton water-side economizer


  • $200,000 Annual Savings
  • 30% Energy Cost Reduction
  • 5-Year Simple Payback Period

The Challenge

How do you grow your network hosting company into an industry leader with a world class data center on a very tight budget, with tight construction schedules? How do you start small, but build in flexibility for rapid growth so you can adapt to changing market conditions? And how do you make that data center an award winner for energy efficiency? These were the questions that NetRiver wanted to answer when they approached PSR Mechanical to help site and design their new facility.

The Solution

NetRiver, starting out as a fledgling tech company, could not get a design commitment from anyone until they approached PSR Mechanical (a Service Logic company) to help them locate a building for their new data center.

PSR started the various feasibility studies in 5 different locations until they finally settled on the REI building in Lynnwood, WA. PSR utilized variable speed pumping for chilled water, variable speed air flow, Smardt chillers with Turbocor compressors and Ultrasonic humidification and hot aisle containment.

The design team, in collaboration with the owner and Snohomish County public utility district, achieved one of the lowest power usage effectiveness ratios in the industry. As a follow up to the project, NetRiver entered into a 5-year full service maintenance agreement with PSR Mechanical, which not only ensures the ongoing energy savings, but also extends equipment warranties.

About the Client

NetRiver is the leading provider of scalable and reliable network-neutral data centers and interconnection services in the Washington area. The newest facility, Lynnwood/Seattle, provides a highly resilient and scalable environment for carriers, internet content companies, hosting firms, and enterprises to scale their operations. Its most salient feature is its high-density design, allowing clients to take maximum advantage of virtualization and blade server technology. Enterprises, content companies, systems integrators and network service providers look to NetRiver for reliability, scalability, and network diversity.

How PSR Mechanical is Supporting Seattle’s Eco-friendly Goals

Published: February, 4 2016

Seattle has recently been recognized in national polls and studies as one of the greenest cities in the nation. With a nickname like “The Emerald City”, it makes sense that Seattle would be working hard to stay “green”. However, the benefits of keeping a city like Seattle ecologically friendly go beyond looking good.

The American Counsel for an Energy Efficient Economy (ACEEE) ranked Seattle #5 in the nation with a score of 75/100 because of its commitment to continue strengthening efficiencies as a strategy for promoting economic growth, securing environmental benefits, and increasing their communities’ resources for exploring new energy sources.

Travel and Leisure rated Seattle #6 in the nation for eco-friendly living because of parks like Gas Works Park, on a former utility-company site, and buildings like the Hyatt. It showcased downtown’s Hyatt at Olive 8, as the first LEED-certified hotel in Seattle thanks to its living roof, water-conserving plumbing and automatic electricity shutoffs.

NerdWallet rated Seattle #9 in the nation saying, “Although the city’s gray skies limit use of solar energy, Seattle makes our list for its air quality, high residential density and commuters who walk and use public transit at above-average rates. In the Emerald City, 9% of workers walk to their jobs and 4% commute on a bike.”

What role do our commercial buildings play in this effort?

Like any active urban area, Seattle is host to hundreds of commercial facilities, from office buildings to hotels, utility plants to manufacturing, and everything in between.

These buildings – where so much of our population spends each work day – are among the busiest and most heavily used spots in the entire city and they have a tremendous impact on the environment. Commercial facilities can take the lead on supporting Seattle’s eco-friendly drive with infrastructure that reduces their impact on the environment, including taking advantage of:

  • Expedited permitting to green building projects.
  • An incentive zoning program that requires developers to provide public benefits to achieve greater height/density on their building site.
  • The Deep Green and Living Building Program, which allows land use departures for both residential and commercial construction that achieve green standards.

This is where PSR Mechanical can help.

PSR Mechanical’s eco-friendly energy services

As a member of the Service Logic family of companies, and one of Seattle’s leading HVAC service providers, PSR Mechanical is in an optimal position to help Seattle’s commercial facilities maintain or improve their interior environment while reducing their impact on the environment outside.

To accomplish this, we combine customized energy programs to optimize building efficiency with the latest technologies and nationally-recognized industry-leading programs (like Energy Star and the U.S. Green Building Council). This powerful combination allows us to maximize current operations while implementing a long term energy sustainability plan.

The end result for our clients – and the city of Seattle as a whole – is a comfortable facility conducive to maximum productivity, reduced operational costs, and a much friendlier environmental impact.
